SIGHT FEED LUBRIOATOR.

ATTESTI PHINEAS A. BENNETT, OF CHICAGO, ILLINOIS, ASSIG-NOR OF ONE-HALF TO THOMAS BENNETT,

OF SAME PLACE.

SlGHT-FEED LUBRICATOR.

S PEC'IPICATIOLT forming part of Letters Patent No. 390.584, dated October 2, 1888.

Application filed May 31, 1888.

To all whom, it may concern.-

Be it known that I, PHINEAS A. BENNETT, a citizen of the United States, residing at Ohicage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sight-Feed Lubricators; and I do hereby declare the following to be afull, clear, and exact description ofthe same, reference being had to the accompanying drawings, [0 forming part of this specification.

This invention relates to that class of lubricating oil-cups in which the oil flows by gravity down through a transparent chamber in its passage from the oil-reservoir to the bearing to be lubricated.

The present improvement has for its object to provide a cup which as a whole is durable and effective in operation and cheap and simple in construction. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1. is an elevation ofa lubricator con structed in accordance with myinvcntion,,and

2 Fig. 2 avertical axial section of the same.

Similar letters of reference indicate like parts in the several views.

Referring to the drawings, A represents the cylindrical glass body of the oilreservoir A,

0 arranged between the upper and lower flanged heads, 13 O, thejoints between the parts being rendered tight by annular elastic washers D D and vertical tie-bolts D that pass down through the interior of the oil-chamber. Such 5 bolts are headed on their upper ends, while their lower ends screw into upwardly-project ing bosses (Z on the lower head, G, as shown.

E is the valve for regulating the flow of the oil from the oilcharnber. This valve is of the needle type, arranged axially in the oil-chamber, its lower or valve end being seated on the upper end of the outlet oil-passage c in the lower head, 0, and its upper end provided with a handle or knob, F, by which it is adjusted. Its longitudinal movement is effected by its intermediate screw-threaded portion,

lice of the upper head, B, B being a packinggland, by which a tight joint is formed around the valve-stem and the proper amount of frictional resistance furnished to afford a sensitive adjustment of the valve.

F is the visible-feed chamber arranged be low the oil-chamber, and consisting of a section of glass tubing, G, inclosed in aslotted tubular metal cage, I-I, thelower end of which is formed with a screw-threaded shank, H, for attachment to the bearing, and having passage L leading from the sight-feed chamber F to the journal or hearing, while its upper end is enlarged and internally screwthreaded to screw upon an attaching-neck, I, on the under side of the head 0.,

The glass tube G rests upon the bottom of the cage, its upper end being packed or held by an annular gasket, J, arranged between the lower face of the neck I and the offset h in the cage, as shown. i is an annular recess in the neck I, to receive the end of the glass tube G, projecting above the packing J.

K is the pendent nipple, through. which the oil is delivered in drops down through the visible-feed chamber F. Such nipple is axially arranged, and is attached in place by being screwed into the under side of the lower head, 0.

M is the hinged cover closingthelillingorifice of the oil chamber or reservoir.

Having thus fully described my said invention, what I claim as new, and desire to secure So by Letters Patent, is

The combination,with the oil-chamber A, the lower head of which is provided with an at taching-neck, I, having annular groove 2' and attached nipple K, of the cage H, having attaching shank H and offset h, gland-packing J, and glass tube G, as described, and for the purpose set forth.

In testimony whereof witness my hand this 22d day of May, 1888.

PHINEAS A. BENNETT.
